OIL-BURNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 791,813, dated June 6, 1905.

' Application filed July 5, 1904. Serial No. 215,252.

To all w/wm may concern:

Be it known that I, JAKE PALMATARY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Oil-Burning Apparatus, of which the following is a specification.

This invention relates to oil-burning apparatus of the general type disclosed in application Serial No. 186,120, filed December 21, 1903. This type of burner is especially adapted for use in bake-ovens on account. of its portability and the fact that it can be moved and regulated to direct its flame to any part of the oven or can be removed bodily from the oven when not in use. The present application shows more particularly its use in this connection.

An important object of the present invention is to make the steam-generator for the burner of extremely simple and yet eflicient construction and to do away with any joints The accompanying drawings illustrate the invention.

Figure 1 is a perspective of the burner apparatus. Fig. 2 is a plan thereof, partly in section. Fig. 3 is aside elevation of the burner in position in a bake-oven, the latter being shown in vertical section. Fig. 4 is a vertical section of the burner-head or jet-piece.

1 designates a supporting-plate, which is also used as a firing-pan, said plate being horizontal and having a raised wall around its edge to form the cup of the pan. Standards 2 2 on this plate have openings 3.to receive the steam-generator 4, to which is connected the water-supply pipe 5, having a controllingvalve 6. A steam-outlet pipe 7 communicates with generator 4 and extendslaterally to connect with the burner 8.

Burner 8 may be of the construction set forth in my aforesaid application, consisting sage 9- and a lower passage 10, these passages being formed as screw-threaded sockets to receive, respectively, the oil-supply pipe 11 and the steam-pipe connection 12, communi- Y eating with pipe 7 The lower passage 10 ter- 1 'in section.

minates in a contracted outlet or orifice 13, which at its forward end expands or flares to form a cup-shaped outlet, and the upper passage 9 communicates with a duct 14, leading downwardly and forwardly into the top of the cup-shaped outlet. A plunger 15 works in a stufiing-box 16 at the rear end of pipe 12 and is operated by a handle 17, the forward end of the plunger entering the outlet 13 when the plunger is pushed in to clean the same.

18 designates a valve for the oil-supply pipe. Water -supply pipe 5 and oil-supply pipe 11 may have flexible supply connections 20 and 21, so that the burner may be shifted from place to place on a suitable support or turned in any direction without interfering with the supply communications. For example, if the burner is used in a bake-oven, to which purpose it is especially adapted, the firing pan or.

plate 1 will rest directlyupen the floor of the oven, (indicated at 22 in Fig. 3,) and the burner 'can be pushed forwardly or rearwardly or to one side or the other, or it can be turned in any direction, so as to heat anydesired part In said figure, 23 designates the flame, so that it will receive heat only by radiation therefrom and not by direct impingement of the flame thereon.

The generator and burner are adjustable relative to the support 1 by moving the generator longitudinally through the standards 2. The same movement serves to adjust the position of the firing-pan relative to the generator and burner. The preferred construction of generator is shown more particularly in Fig. 2, where the generator is shown partly Said generator compri sesan outer adapted to receive an extension 25 of the water-supply pipe 5, which passes therethrough and is held thereby centrally or axially of the outside tube or pipe 24:, the inner pipe 25 extending approximately to the forward end of the outer pipe, so that the inner and outer pipe members 25 24: form, respectively, outgoing and return portions of a conduit leading from the water-Suppl y to the steam-outlet. The generator is preferably given a drop or dip forwardly sufficient to insure that any water that may exist in the outer pipe will collect in its forward end, so that the rear end thereof, from which the steam is drawn, will always be free of water. The steam-outlet 7 preferably leads from the top of the outer pipe 24:. A blow-off cock 28 is provided in the bottom of tube 4 near the front end thereof.

The apparatus is used as follows: Assuming it to be placed in a bake-oven, a small quantity of oil, which may be distillate or other suitable oil, is turned on by opening the -valve 18, the oil flowing into the firing-pan,

where it is ignited and serves to heat the generator to the proper temperature. The water is then turned on by opening the valve 6, and passing inwardly through the extension 25 of pipe 5 it traverses substantially the entire length of the generator and absorbs heat by radiation from the outer walls thereof, finally dropping into the outer tube of the generator at the forward end thereof and passing backwardly along said outer tube. The generator is of suflicient heat-absorbing capaeity to convert all of the water thus supplied into steam before it has passed any considerable distance in its backward course along the outer tube, so that said outer tube is substantially filled with steam. The steam passes from the top of the outer tube, through connections 7 and 12, to the outlet 13 of the burner.. The oil being turned on by opening the valve 18 flows downwardly through the inclined duct 14 onto the escaping and extending jet of steam and is carried forward and atomized thereby. This jet of atomized oil is ignited as it passes over the flring-pan and produces a flame which extends parallel to the generator 4, but does not directly impinge upon the same. The length of the flame can be regulated by adjustment of the supply of oil by means of valve 18. It will be seen that all the joints in the steam-generator are removed a sufficient distance from the flame to remain comparatively cool, and the portion of the generator which extends in proximity to the flame has no joints which would be liable to cause deterioration under the action of the heat.

What I claim is 1. An oil-burner comprising a horizontal plate having a raised wall to form the cup of a firing-pan, said plate having standards extending upwardly therefrom, a steam-generator formed of an outer pipe supported on said standards at definite height above the firingpan and a pipe extending interiorly of the aforesaid pipe, a water-supply connection for said interior pipe, a burner-head having oil and steam outlets, an oil-supply connection to said oil-outlet and a steam-supply connection from the outer pipe of the generator to the steam-outlet of the burner-head, said burnerhead being supported from the generator by the steam-supply connection therefrom.

2. An oil-burner comprising a horizontal plate having a raised wall to form the cup of a firing-pan, said plate having standards extending upwardly therefrom, a steam-generator formed of an outer pipe supported on said standards at definite height above the firingpan and a pipe extending interiorly of the aforesaid pipe, a water-supply connection for said interior pipe, a burner-head having oil and steam outlets, the oil-outlet being below and in proximity to the steam-outlet, an oilsupply connection to said oil-outlet and a steam-supply connection from the outer pipe of the generator to the steam-outlet of the burner-head, said burner-head being supported from the generator by the steam-supply oonnection therefrom.

3. An oil-burner comprising a horizontal plate having a raised wall to form the cup of a firing-pan, said plate having standards extending upwardly therefrom, a steam-generator formed on an outer pipe supported on said standards at definite height above the firingpan and a pipe extending interiorly of the aforesaid pipe, a water-supp] y connection for said interior pipe, a burner-head having oil and steam outlets, the oil-outlet being below the steam-outlet and expanding at its forward end to form a cup-shaped outlet into which the steam-outlet opens, an oil-supply connection to said oil-outlet and a steam-supply connection from the outer pipe of the generator to the steam-outlet of the burner-head, said burner-head being supported from the generator by the steam-supply connection therefrom.

In testimony whereof I have hereunto set my hand, at Los Angeles, California, this 25th day of June, 1904.
